Process of preserving manufactured or leaf tobacco



No Drawing.

To all whom it may concern: 7

Be it known that we, VICENTE CATALA AL- SINA and GENARO FERNANDEZ, subjects of the King of Spain, residing in the city of Buenos Aires, Argentine Republic, have invented a new and useful Process of Preserving Manufactured or Leaf Tobacco, of which the following is a specification.

Tobacco, as other plants, is composed of 'two groups of substances, the organic substances which disappear in the form of gases on combustion, and the mineral substances, which remain after combustion forming the ash. The freshly cut leaf, taking an average the following figures:

Water 88%, organic matter 11%, mineral matter 1%, total 100%. The already dried leaves (air dried) give, on calcination, 22% of ash, which is apparently formed by the mineral acids, sulfuric, nitric, hydrochloric and phosphoric, combined with alkaline bases, ammonia, potash, lime, magnesia, and iron. Silica is always present and. soda and manganese frequently found.

The principal organic compounds are cellulose, lignin, gums, the vegetable acids (malic, citric, oxalic and pectic) combined with the mineral bases mentioned and with the organic base or specific alkaloid of tobacco, nicotin.

The greater portion such as the cellulose, acids are found in all invariable proportion;

of these compounds, lignin and organic tobaccos in almost others, such as the mineral bases and the nicotin are extremely.

variable, imparting distinctive the various kinds of leaf.

During the fermentation of the tobacco a part of the organic acids present are converted into nicotin compounds, to which the fermented (ripened or cured) tobacco owes its special aroma. During the fermentation of the tobacco a portion of the nicotin is decomposed, forming ammonia, a part of which is converted into ammonium compounds and a part of which vaporizes, while the unclecomposecl nicotin is largely converted into organic compounds of nicotin. A small part of the nicotin also evaporates and is thereby lost during fermentatlom 1 After careful study and extensive expenmentation, we have found that the destrucproperties to tion of tobacco by the insects known as VICENTE CATALA nLsInA' AND GENARG FERNANDEZ, 'orrunnos Alan's,

by the lack of heating properties in the tobacco, and the tobacco which has the neces-' sary heating properties will not be injured by these insects.

We have further found that the necessary heating properties can be added to the to to the action of vanilla and tonka bean. .Forth'is purpose we employ the dried fruits of the arcmatic vanillafiwartz or the Vanilla plan ijolz'a Andrews or Mexican (commonly called aromatic) vanilla, and also the dried fruits of the Dz'ptcrg x odo'mta (commonly called tonka, Turkish or Kamerun bean).

other plants having the same or similar properties.

We have found that for the preservation of a bale of tobacco weighing 45 kilograms, 6 grams of vanilla and 2 grams of tonka are sufiicient. In employing these materials we preferably mix the vanilla, grind or comminute the material, and after mixing, divide the quantity into three approximately equal parts. For manufactured tobacco, on account of the fact that this has already had much more contact with air and moisture, during the process of manufacture, as well as while being pressed and treated, 500 milligrams of the mixture of vanilla and tonka (for example 300 milligrams of Va nilla and 200 of tonka) should be employed for each box of 100 plugs of tobacco. V

In destroying the aforesaid materials in the bale of tobacco, we preferably place the materials put up in three separate packages, in three widely separated places in the bale. Thus we may place one of the packages near the bottom, one near the mid die and one near the top of the bale. In preserving manufactured tobacco, we preferably proceed in the same way, placing the we likewise include the fruits of comminuted materials in perforated tin foil 7 ;tured tobacco, it is preferable to leave the v or sold. a V

In both cases the packages of vanilla and,

packages of vanilla and tonka in the boX-of tobacco until the entire box has been used tonka, when removed from the tobacco may be employed again,providec l they are kept dry-and in a sealed container.

Tobacco treated in this way is found to be not only of very greatly improved aroma and flavor, but also is the other insects above referred to.

The term manufactured tobacco as herein employed is intended not only to cover plug tobacco, but also cigars, ciga rettes, etc. c

What we claim is:

A process of preventing injury to tobacco found to be entirely. immune to attack by the tobacco moth and products, by the tobacco moth and other similar insects, which comprises subjecting the tobacco products to the odors emanating froma mixture comprising a mixture of being placed in oroximity with the said tobacco products, out being protected from actual contact therewith, and allowing the tobacco products to absorb said odors.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
